In the steady-state case we associated this electric field with a potential difference in volts, ΔV = − ∫ABE · ds. We further identified the potential with the potential energy of a charge q as U = qV. However, as we shall see later, it is possible to create electric fields, such as by magnetic induction, that are not conservative, and for them there is no potential energy to be def…Next Chapter >< Previous Chapter
